Redline Communications …..solving the first mile challenge .
LOS
Line Of Sight. A clear direct path between two antennas, with
no obstructions within the first Fresnel zone.
MAC (Media Access Control) A unique number assigned to a network device. It corresponds
to the ISO Network Model Layer 2 data link layer.
MHz Megahertz. 1,000,000 Hz
Modem
(MOdulator/DEModulator) A hardware device which converts digital data into analog and
vice versa.
Modulation Any of several techniques for combining user information with a
transmitter carrier signal.
Multipath The radio echoes created as a radio signal bounces off of
objects.
NLOS Non Line Of Sight. Completely obstructed path between two
antennas.
OFDM Orthogonal Frequency Division Multiplexing. OFDM spreads
data to be transmitted over a large number of orthogonal
carriers.
OLOS Optical Line Of Sight. A clear direct path between two
antennas, with obstructions within the first Fresnel zone.
Packet A bundle of data organized in a specific way for transmission.
The three principal elements of a packet include the header,
the text, and the trailer (error detection and correction bits).
PHY (Physical Layer) Provides for the transmission of data through a
communications channel by defining the electrical, mechanical,
and procedural specifications.
PMP Point to Multipoint
PTP Point to Point
QAM Quadrature Amplitude Modulation
QoS Quality of Service
QPSK Quadrature Phase Shift Keying
Receiver Sensitivity A measurement of the weakest signal a receiver can receive
and still correctly translate it into data.
RF Radio Frequency
Rx Receiver
S/N Signal to Noise Ratio
SINADR Signal to noise and distortion ratio.
SS Subscriber Station
TCP/IP (Transmission
Control Protocol/Internet
Protocol) The standard set of protocols used by the Internet for
transferring information between computers, handsets, and
other devices.
TFTP Trivial File Transfer Protocol
Tx Transmitter
